I recently installed VS2022. I have a .sln than runs on VS2019. When I try to load it into VS2022 a screen comes up with a green attachment arrow near the top. I click on it and get a list of possible attachments. None that I have tried work. What should I attach?

    Thanks for reaching out. You’ve mentioned about a green attachment arrow and a list of possible attachments- which usually appear when debugging or running a project that is not correctly configured. Here’s how to fix it-

    1.      Open solution in VS2022 properly

    ·         Instead of double-clicking the .sln file, open Visual Studio 2022 first.

    ·         Go to file-> Open-> Project/Solution….

    ·         Select your .sln file.

    2.      Check the Project Compatibility

    ·         If prompted to upgrade, let VS2022 upgrade the project files.

    ·         Some SDKs or workloads might not be installed- check for errors in the Output or Error List window.

    3.      Install missing Workloads

    ·         Go to

    Tools-> Get tools and features….

    This opens the Visual Studio Installer.

    ·         Make sure all relevant workloads (like .NET desktop development, ASP.NET, C++ etc.) are installed.

    ·         VS2022 sometimes can’t load a project if its required workload is not installed.

    4.      Clean and Rebuild

    ·         Open opened, do:

    Build-> Clean Solution

    Then Build-> Rebuild solution.

    5.      Green Arrow Issue (Debug Target not Set)

    ·         The green play button (arrow) shows the current startup project.

    ·         Right-click your main project in Solution Explorer-> Set as Startup Project.

    ·         Then try to run (press F5).

    6.      If attach option appear instead of Running

    ·         That means there’s no executable startup project.

    ·         Check the project type- for example, if it’s a class library, it can’t be run directly.

    ·         You must select or create a runnable project (like a console app, web app, or test project).

    Reference docs:

    ·         Modify Visual Studio Workloads and Components | Microsoft Learn

    ·         Set multiple startup projects - Visual Studio (Windows) | Microsoft Learn
